Endornaviridae

A site specific break (nick) is found in the coding strand about 1 to 2 kb from the 5’ terminus.

ViralZone conflicts with ICTV, listing Endornaviridae as dsRNA viruses.

[1][2] As the Endornaviridae genomes don't include a coat protein (CP) gene, they no true virions are associated with members of this family.

For Vicia faba endornavirus, the RNA genome has been associated with some pleomorphic cytoplasmic membrane vesicles.

[2][1] As the replicative dsRNA form is relatively stable, it can be found in comparatively high quantities in host tissues, and therefore is a likely subject of isolations[1] (this is the reason why Endornaviridae often are classified as dsRNA viruses,[2] in contrast to the official ssRNA(+) ICTV classification).
